Title: Control device of fuel supply to combustion chamber of gas turbine plant
Inventor: KUPRIK VIKTOR VIKTOROVICH
IPC: F02C9/26
Filed: 2008-12-09
Granted: 2010-06-20
Abstract: FIELD: engines and pumps. 
     SUBSTANCE: invention refers to control methods of fuel supply to combustion chamber. Method involves the change of fuel flow to collectors of fuel circuits of combustion chamber depending on the power of the plant. When implementing the method, there pre-introduced is combustion chamber to pulsating combustion area; pressure and level of pressure pulsations in combustion chamber is measured, and when level of pulsations is more than 1% of the pressure value in combustion chamber, there fixed is minimum amplitude of vibrations of the engine housing in the area of combustion chamber with vibration detector within 350-900 Hz, and that value is accepted as maximum allowable. During operation of the plant there measured is amplitude of vibrations of engine housing in combustion chamber area, and when it exceeds the maximum allowable value in the chosen range of frequencies, there additionally measured is fuel flow at least to one collector till vibratory combustion is eliminated; after that fuel flow to fuel collectors is recovered to the initial level. Change of fuel flow to collectors of fuel circuits can be performed by means of fuel redistribution between fuel collectors.
